Modular backpacks focuses entirely on one backpack and making that the best it can be. Instead of direct upgrades, backpacks use a swappable module system that lets you build your own backpack tailored to your playstyle. Enchantments can even change how your backpack functions entirely.
This mod is primarily designed to be an in-depth and (somewhat) balanced alternative to other backpack mods, with some more Vanilla-esque design mannerisms.
